Raspberry plant named ‘Advabertwee’

ABSTRACT

A new and distinct cultivar of Raspberry plant named ‘Advabertwee’, characterized by its upright and somewhat open plant habit; freely branching habit; high fruit production; uniform fruit ripening; large firm bright red-colored fruits; pleasant and sweet fruit taste; and good fruit postharvest longevity.

Botanical designation: Rubus idaeus.

Cultivar denomination: ‘ADVABERTWEE’.

The present application is a reissue application of U.S. Plant Pat. No. 23,914, issued Sep. 24, 2013, from application Ser. No. 13/385,295, filed Feb. 10, 2012, the content of each of which is incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Raspberry plant, botanically known as Rubus idaeus and hereinafter referred to by the name ‘Advabertwee’.

The new Raspberry plant is a product of a planned breeding program conducted by the Inventors in Rossum, Gelderland, The Netherlands. The objective of the breeding program was to develop new Raspberry plants with good fruit quality, productivity and uniformity.

The new Raspberry plant originated from a cross-pollination made by the Inventors during the spring of 2007 of a proprietary Raspberry selection identified as code number 207157-12, not patented, as the female, or seed, parent with a proprietary Raspberry selection identified as code number 207015, not patented, as the male, or pollen, parent. The new Raspberry plant was discovered and selected by the Inventors as a single plant from within the progeny of the stated cross-pollination in a controlled environment in Rossum, Gelderland, The Netherlands in September, 2008.

Asexual reproduction of the new Raspberry plant by root cuttings in a controlled environment at Rossum, Gelderland, The Netherlands since the spring of 2009 has shown that the unique features of this new Raspberry plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Raspberry have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Advabertwee’. These characteristics in combination distinguish ‘Advabertwee’ as a new and distinct Raspberry plant:

-   -   1. Upright and somewhat open plant habit.     -   2. Freely branching habit.     -   3. Moderately high fruit production.     -   4. Uniform fruit ripening.     -   5. Large firm bright red-colored fruits.     -   6. Pleasant and sweet fruit taste.     -   7. Good fruit postharvest longevity.

Plants of the new Raspberry differ primarily from plants of the female parent selection in fruit size as fruits of plants of the new Raspberry are larger than fruits of female parent selection.

Plants of the new Raspberry differ primarily from plants of the male parent selection in rooting habit as plants of the new Raspberry produce more adventitious buds than plants of the male parent selection.

Plants of the new Raspberry can be compared to plants of Raspberry ‘Polka’, not patented. In side-by-side comparisons conducted in Rossum, Gelderland, The Netherlands, plants of the new Raspberry differed from plants of ‘Polka’ in the following characteristics:

-   -   1. Plants of the new Raspberry were more open than and not as         bushy as plants of ‘Polka’.     -   2. Plants of the new Raspberry were more freely flowering than         plants of ‘Polka’.     -   3. Plants of the new Raspberry flowered later than plants of         ‘Polka’.     -   4. Fruits of plants of the new Raspberry were lighter in color         and heavier than fruits of plants of ‘Polka’.     -   5. Fruits of plants of the new Raspberry did not become darker         in color after harvest whereas fruits of plants of ‘Polka’         became darker in color after harvest.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and measurements describe plants grown during the summer and autumn in 10-liter containers in an outdoor nursery in De Kwakel, The Netherlands and under typical commercial production practices.
